It is an excellent tablet. If you have an issue they will replace it. Use the device and draw your own conclusions. Nvidia has a lot of devices out there and this is just one thread with one disgruntled customer. No company is perfect and in my case at least they have done what needed to be done for my issues.
Thanks for the reply. I'm still undecided on whether or not to send it back. I've taken it out of the box, but left it in the wrapper and ha a bit of a play with it. It's fast! Very fast! Speakers sound amazing. I like that it can take a 128gb sd card so I can put plenty of media on there. I'm just really worried about the cracking issue. What issue did you have?
